Home Working Conference Audio Monitoring

Conference calls taken at home are becoming more and more important, as part of the general trend of increased home working. There are huge cost benefits in hosting conference calls over the internet, as opposed to dialing into a traditional bridge with a landline or mobile. However, when the network or the conference system itself becomes congested, quality can suffer, leading to drops in productivity and in extremes, a completely unusable service.

For those enterprises increasingly depending on conference calls, the key question is:
“How can I measure and monitor the audio quality of my conferencing system such as Zoom, WebEx, GoToMeeting, BlueJeans, Skype or MS Teams?”

The critical point, is to get ahead of users, avoiding wasted time and lost productivity. Instead, find issues proactively and take corrective steps before users try to hold a conference call.

Audio Measurement 101

Much research has been conducted into measuring audio quality, initially this was based on humans listening in highly controlled conditions and rating the quality manually. It has since been modelled mathematically and can now be computed. The high level result of this research, is the MOS system. MOS stands for Mean Opinion Score and it ranges from 1 (bad) to 5 (excellent). A perfect five is hard to achieve in real world conditions.

A MOS value of about 2 or less will make a conference call inefficient, likely to end in failure and a complaint into a support team to investigate.   Measuring the MOS of your conferencing system over time is critical to ensure it is working efficiently, to evidence an issue to the provider, or to help make the correct decision to switch supplier.

Opale Systems software based audio quality monitoring

To meet all of the requirements for audio quality monitoring, Frame Communications partners and recommends Opale’s MultiDSLA product suite.  

Opale’s VoxPort Packet “VPP”, is a software based solution, deployed in a Windows environment and able to simulate and measure real audio incredibly flexibly.  VPP nodes are deployed as required, centrally controlled by the DSLA Controller and can then make and receive SIP and VoLTE calls, either to each other, or into conference systems.
